dynamic_sidebar() is really old function by now, it's well time to stop checking if it exists. :) This just gets passed on as arcane spell...

fair enough I've just had the snippet stored for a while and haven't bothered to change it.

Oh my God, I've been so blind ;/ In fact I found the same code @curtismchale gave in my own sidebar.php file... Just moved it from there to page.php... Thanks a lot guys, +1 :)

@Wordpressor rather than moving it to page.php you should stil call get_sidebar() and put your conditionals in sidebar.php.
